PARAMETER –
sip transport protocol
CONFIGURATION FILES
startup.cfg, <model>.cfg, <mac>.cfg
DESCRIPTION
The protocol that the IP phone uses to send out SIP messages.
Notes:
• If you set the value of this parameter to 4 (TLS), the phone checks
to see if the “
sips persistent tls
” is enabled. If it is enabled, the
phone uses Persistent TLS on the connection. If “
sips persistent
tls
” is disabled, then the phone uses TLS on the connection. If
TLS is used, you must specify the Root and Intermediate
Certificates, the Local Certificate, the Private Key, and the
Trusted Certificates.
• If the phone uses Persistent TLS, you MUST specify the Trusted
Certificates; the Root and Intermediate Certificates, the Local
Certificate, and the Private Key are optional.
• This parameter implies keep-alive mechanism.
For more information about Persistent TLS, see
